Overview
The MC74VHC240DWR2G is an octal inverting buffer and line driver manufactured by onsemi, belonging to the 74VHC logic series. It features a wide supply voltage range of 2 V to 5.5 V and operates within a temperature range of -40°C to +85°C. The device provides three-state outputs with high drive capabilities, delivering 8 mA at both high and low states. Packaged in a 20-SOIC surface-mount format, it includes eight input lines and eight output lines.
Feature Summary
- Octal configuration providing eight independent inverting buffer channels
- Three-state output capability for bus-oriented applications
- Wide operating voltage range supporting 2 V to 5.5 V supplies
- High current drive strength of 8 mA per output
Applications
- Bus-oriented memory and signal switching
- Clock drivers and buffering
- High-speed data transmission lines
Procurement Notes
Verify RoHS compliance status directly with the manufacturer or authorized distributors, as environmental declarations can change. Confirm the specific package variant matches design requirements. Check for any recent Product Change Notices (PCN) regarding manufacturing location or material updates before finalizing procurement plans.
Selection Notes
Select this component when an octal inverting buffer with three-state control is required. Ensure the system voltage falls within the 2 V to 5.5 V range. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify propagation delay specifications against timing requirements if high-speed performance is critical.
Part Context
This part belongs to the 74VHC family of high-speed CMOS logic devices. It serves as a direct replacement for older non-RoHS versions like the MC74VHC240DWR2. The 'G' suffix typically indicates Green/RoHS-compliant packaging. It shares functional similarities with other octal buffers but offers improved speed and lower power consumption compared to standard HC series.
Replacement Considerations
MC74VHC240DTR2G is a direct pin-compatible substitute in TSSOP-20 packaging.
